respectively. A quantitative structure-activity relationship (QSAR) study of these synthetic derivatives as well as wogonin indicated that high solubility and low octanol/water partition coefficient are favorable, and excessive electrostatic properties and refractivity are unfavorable for the cytotoxic activities of these wogonin derivatives. These findings and results provide a base for further investigations
通过在wogonin的7、8或B环上引入基团,合成了一系列新的49种wogonin衍生物。还体外研究了对HepG2,A549和BCG-823癌细胞系的细胞毒活性。其中一些具有明显的细胞毒性活性,化合物3h对HepG2,A549和BCG-823的效力最高,IC50值分别为1.07μM,1.74μM和0.98μM。对这些合成衍生物以及沃戈宁的定量构效关系(QSAR)研究表明,高溶解度和低辛醇/水分配系数是有利的,过多的静电性能和折射率不利于这些沃戈宁衍生物的细胞毒性。这些发现和结果为进一步的研究奠定了基础。
